dominated by Coal.
“When we do modelling where we increase the renewable penetration above around 40 per cent of the energy delivered (where South Australia is now) that starts to force out some of that existing dispatchable generation, and then we find that you need to add other technologies to support renewables,’ Graham said.
“That can include storage, as we have been talking about, and there are a number of different storage technologies.
“It can also mean adding other dispatchable renewables. We often think about solar thermal as a dispatchable renewable, and there are geothermal technologies.”
